Patent DE-2125712-A1 (DE)
Title: Heat-treatment chamber - for nap material partic polyacrylonitrile pile fibres
IPC: D06B23/18
Filed: 1971-05-25
Abstract: Heat-treatment chamber employing steam or hot air for the treatment of textile widths has an outlet for the material which is sealed gas-tight to an associated fluid-treatment bath, in which the nap material, partic. polyacrylonitrile pile, is treated in a guideway through which the fluid flows. The material comes to rest with the surface opposite the pile on the guideway, which is pref. a revolving screen drum, and the material is then led off in a direction opposite to that of the general direction of its movement through the installation as a whole. The fluid bath has devices, pref. heaters, which ensure that the material only cools gradually. In the heat-treatment chamber and between this and the bath, no object comes into contact with the pile. This prevents pile deformation and enables the material to be wound ready for sale as soon as it has dried.

Title: Steering mechanism for track-laying vehicles - requiring only one foot to brake drive on either side by mechanical linkage
Inventor: PELESKA VACLAV
IPC: B62D11/08
Filed: 1973-03-05
Abstract: Declutching of the drive on either side is hydraulic whilst braking of the track is by direct mechanical linkage with the pedal. Two wide pedals are mounted side by side both for operation by the right foot. The adjacent parts of the pedal faces are recessed so that the foot may readily find this surface and press both together. Initial, light, movement of one pedal first operates the hydraulic spool valve and declutches on one side. Further, heavier, movement applies the brake on that side. Press. on both pedals together operates both clutches and both brakes and brings the tractor to rest.

Title: Tubular bag liquid filling system - valve inserted initially almost to bag base and then steadily withdrawn
Inventor: NEUHAUS FRANZ PETER
IPC: B65B9/213
Filed: 1973-11-09
Abstract: The system is for use with liquids and pastes, having a vertical filling valve, a metering device stopping the flow when the bag is full, and a welding device sealing the filled bag. When filling, the valve outlet is inserted in the bag nearly as far as its base weld seam, and it is then continuously raised so as to keep the same distance between the fluid level and the outlet. On completion of filling, the valve is retracted above the welding device. The valve can be raised by a pneumatic or hydraulic ram, or a motor-driven screwed spindle. The advantage is that moistening by the contents of the area to be welded is avoided.

Title: Asynchronous audio pulse coded modulator - converts audio signals into binary pulses with duration proportional to input signal
Inventor: MATT HANS JUERGEN DIPL ING
IPC: H03M3/02
Filed: 1974-02-28
Abstract: A high quality asynchronous pulse coded modulator applicable to audio frequency input signals is presented. The input signal is fed into one input of a linear amplifier based comparator. The output of this is fed to a Schmitt trigger circuit via a low pass filter. The Schmitt trigger exhibits a carefully controlled hysteresis so that it produces an output when the input exceeds a certain threshold, but reverts to null output only where the input is less than some smaller fixed threshold. The Schmitt trigger output is the required signal and is also fed to the second input terminal of the input comparator, via an integrator. The exact frequency attained depends on the characteristics of the filter and integrator.

Title: Lawn mower power cable reeling equipment - has reduction gear and magnetic clutch between motor and cable drum
Inventor: LURZ KLEMENS DIPL ING
IPC: B65H75/42
Filed: 1974-03-01
Abstract: The mechanism incorporates a reduction gear drive between motor and cable drum, also a magnetic clutch, particularly of the eddy-current type. Motor and drum can be coaxial. A guide tube can be mounted in front of the drum with a funnel-shaped mouth extending both vertically and horizontally. A guide shoe can be mounted between drum and tube parallel to the drum axis. This is pressed by the cable running over it against that already on the drum, so as to feed the cable on and off at an angle to the drum axis. The design enables winding of the cable to be carried out at low power outputs, e.g. when the motor is idling and the lawn-mower is being moved over grass which has already been cut.

Title: Controller for D.C.SERIES TRACTION MOTOR - uses single series rheostat with selector switches for all operating conditions
Inventor: CIESSOW GUENTER ING GRAD
IPC: H02P3/14
Filed: 1974-06-21
Abstract: The apparatus reduced the equipment required for normal and emergency running and regenerative braking in a traction control system using a thyristor regulator to control the average voltage applied to the motor. By suitable switching a single rheostat (4) may be used for all duties. For example with switch (14) closed the circuit is connected for normal operation in forward or reverse direction depending on the position of the reversing switches (10-13). For regenerative braking switch (15) is closed to complete the circuit to the d.c. source (1) via the filter (2, 3). Emergency operation, in which the thyristor controller (7,8) is out of service, is obtained by closing switches (16) and (18). The rheostat can also be short circuited as required by a further switch (17).
